One of the widest soundstages in its price class — a competitive gaming staple for over a decade. The stock treble peak and bass shelf are corrected by the StepFreq profile, delivering fatiguing-free positional audio optimised for footstep detection.
These filters are applied first — they flatten Beyerdynamic DT 990 Pro's frequency response to neutral. A game-specific footstep boost layer is then added on top. Both are baked into the downloaded config.
